PHILIP A. FUCHS, OF MILWAUKEE, WISCONSIN.

PULLEY-SUPPORTING BRACE.

To all whom it may concern:

Be it known that I, PHILIP A. FUCHS, a citizen of the United States,residing at Milwaukee, county of Milwaukee and State of Wisconsin, haveinvented new and useful Improvements iny PuilleyeSupporlting' Braces, ofwhich the following is a specification.

My invention relates to improvements in pulley-supporting braces fortube systems.

The object of my invention is to provide removable means for supportinga pulley near the bottom of a catch basin or man hole pit of a seweragesystem or any other system of pipes or tubes in which it is desirable todraw cleaning apparatus through the pipes or tubes at intervals. Myinvention makes it possible to sup-port a pulley in such a position thata cable may be drawn through the sewer or horizontal pipe and passedaround the pulley and upwardly to the exterior through a man hole orcatch basin, whereby cleaning apparatus having another cable and a hoseattached thereto may be guided into the sewer from another catch basinor man hole as the cleaning apparatus advances, the apparatus beingadvanced or retracted by means of the cables and the hose being used todeliver water to the apparatus for power or iushing purposes.

The drawing illustrates my improved apparatus in elevation as loca-tedfor use within a sewer system, fragments of the sewer pipes and of apair of man holes or catch basins being illustrated in vertical section.

In the drawings, each man hole or catch basin communicates at the bottomwith pipe sections 2, 3 and 4 respectively. My mproved brace is formedin telescoping sections 5 and 6, the lower section 5 being pivotallyconnected at 7 with a shoe 8 adapted to rest upon the bottom of thesewer. The lower section 5 is also provided with a. bracket 9 in which ahook arm 10 may engage, this arm having swivel connection with a pulleyblock 11 in which a pulley 12 is journaled. The bracket 9 is preferablyin the form of a staple, the two legs being passed through apertures inthe section 5 of the brace near its lower end and threaded to receivethe nuts 13.

The upper section 6 of the brace is provided with a series of apertures14 adapted to receive a pin or bolt 15 which extends through a boltreceiving aperture in the Specification of Letters Patent. Patenteddipl. 29, lllillldl.

upper end of section 5. In the drawing, this connection is illustratedas a bolt 15 threaded to receive a nut 16, whereby the sections 5 and 6of the brace may be securely locked together. The upper end of the bracesection 6 is flattened as illustrated at 17 and provided with a wedgeshaped extremity adapted to engage against orbetween the bricks orblocks forming the wall of the man hole or catch basin.

By forming the brace in adjustable sections, it is possible to utilizeit in catch basins or man holes which differ in diameter. The sectionsare of such length that the braces may be readily manipulated to theposition in which they are illustrated in the drawings. The shoe 8 maybe pushed into one of the sewer pip for a short distance, with section 5of the brace extending upwardly therefrom in an inclined position. Thesection 6 of the brace may be extended in correspondence with thediameter of the catch basin or man hole and it may either be extendedafter the shoe 8 has been placed in position as illustrated in thedrawing, or if desired, the section 6 may be adjusted to the properposition before inserting the brace. In either case, the section 6 willbe extended sufciently to support the brace in an inclined position withits upper end in anchorage engagement with the wall of the catch basinor man hole.

The pulley 11 is supported by the brace in a position to receive anactuating cable 20 which cable extends from the cleaning apparatus 21through the sewer pipe 3, around the pulley and vertically through theman hole 1. The pulley is adapted to receive the cable in such a.position that when the latter is drawn upwardly the force exerted uponthe pulley will not only increase the pressure of the wedge shaped upperextremity against the wall of the basin, but owing to the proximity ofthe pulley to the lower end of the section 5, the shoe will be drawnforcibly downward into contact with the bottom of the sewer, due to theresultant force exerted on the pulley. The apparatus may be retracted bya retracting cable 22 extending to the rearward catch basin or man hole.

It will be observed that the cables are operated by means of windlasses28 located above the respective man holes. Only one brace is required,when the apparatus is being advanced, viz: that at the man hole in frontof the machine (shown at the left in the drawing). But where theapparatus is to be retracted, asimilar brace will be used in the otherman hole. The hose pipe 24 may be coupled at intervals to the retractingcable 22, whereby the Cable may be utilized to withdraw the hose. Insuch case, the hose will be uncou-p-led from the cable as it reaches theexit, thus allowing the cable to pass around the pulley.

I claim:

The combination with a sewer cleaner, of a cable for drawing the sainethrough the sewer, a pulley supporting brace adapted to extend obliquelyfrom the bottom of the sewer adjacent to the Inan-hole,\across themannhole into Contact with its opposing wall, a pulley connected withthe brace in a position to be supported thereby near the lower endthereof and adjacent tol one wall of the man-hole, said cable beingextended around said' pulley and upwardly through the man-hole andadapted to draw the up# per endof the brace against the opposing wall,and the lower end of the brace against the bottom of the sewer, saidbrace having a pivoted foot. piece at its lower end, and an extensiblesection at its upper end terminating in a wedge shaped extremity adaptedfor biting anchorage in the wall of the man-hole.

In testimony whereof I affix my signature in the presence of twowitnesses.
